Lately I've noticed my /dev/nvidiactl is getting permissions of crw------- 1 root root 195, 255 Nov 15 14:19 /dev/nvidiactl I believe this started happening after the pam pam_console updates. To try to troubleshoot the problem first I looked at: sbh@rocket ~ % grep '<dri>' /etc/security/console.perms.d/50-default.perms <dri>=/dev/nvidia* /dev/3dfx* /dev/dri/card* <console> 0600 <dri> 0600 root I think this is the problem. I don't have any boxes that have the old default.perms file on it, but I believe it was different. After changing to: crw-rw---- 1 root games 195, 255 Nov 15 14:19 /dev/nvidiactl the game works fine. Thanks.
